Feature Description
When a call that is made from the ISUP (ETS_300_356) to the Session Initiation Protocol (SIP) is redirected to the ISUP (ETS_300_356), the following information is sent in Initial Address Messages (IAM) or Address Complete Messages (ACM):
•
•
•
•
•
The Suppression of Redirecting Number and Information feature enables the optional suppression of the above parameters in IAMs and ACMs. In incoming messages, these parameters are parsed and processed for all existing call logics. The decision about suppression is taken when encoding or packing the ISUP messages in the outgoing direction of the Cisco PGW 2200 Softswitch. The ISUP trunk group properties are used to configure the suppression.
